With the Gratical Eye, Zacuto takes the highly regarded 0.61", 1280 x 1024 micro OLED panel found in their Gratical HD and packs into an EVF that weighs just 14 oz and fits into the palm of your hand. In order to keep the EVF small and compact, it features a round design and it equipped with only a single 3G-SDI input that supports up to 1080p60 video, a 2-pin LEMO power connector, and a USB port for firmware updates. Not content at being just a professional-grade EVF that produces natural looking images with a 10,000:1 contrast ratio, the Gratical Eye is equipped with a FPGA dual core processor to support the full set of monitoring and image analysis features found on the larger Gratical HD, including LUT support, vectorscope and waveform displays, and peaking, which are controlled using a joystick-style button on the back of the unit. With its compact size and full feature set, the Gratical Eye is an EVF ideally suited for use with professional SDI cameras
